Alginate oligosaccharides (AOS) are degradation products of alginate extracted from brown algae. With low molecular weight, high water solubility, and good biological activity, AOS present anti-inflammatory, antimicrobial, antioxidant, and antitumor properties. They also exert growth-promoting effects in animals and plants.

Abstract To investigate the prebiotic potential of alginate oligosaccharides (AOS), prepared through enzymatic hydrolysis of alginate polymer, the effects of AOS on bacterial growth were studied. In vitro studies showed that the numbers of bifidobacteria or lactobacilli were greater than those in control medium when they were cultured in the medium ...

Production of Oligosaccharide from Alginate Using Pseudoalteromonas agarovorans
Applied Biochemistry and Biotechnology, 2009A marine bacterium was isolated from seawater near the Korean south coast for efficient saccharification from alginate. Based on 16S rDNA sequence, the isolated strain was identified as Pseudoalteromonas agarovorans. Various environmental factors affecting saccharification of alginate using P. agarovorans CHO-12 have been investigated in flask cultures.

Alginate Oligosaccharides: Enzymatic Preparation and Antioxidant Property Evaluation
Food Chemistry, 2014Alginate oligosaccharides (AOs) prepared from alginate, by alginate lyase-mediated depolymerization, were structurally characterized by mass spectrometry, infrared spectrometry and thin layer chromatography. Studies of their antioxidant activities revealed that AOs were able to completely (100%) inhibit lipid oxidation in emulsions, superiorly to ...

Preparation and Structure Elucidation of Alginate Oligosaccharides Degraded by Alginate Lyase From Vibro sp. 510 [PDF]
Carbohydrate Research, 2004 Alginate that was purified from the fermentation solution of marine bacteria Vibro sp. 510 under specific reaction conditions was hydrolyzed by alginate lyase. Seven oligosaccharides, including di-, tri- and tetrasaccharides, were isolated through low-pressure, gel-permeation chromatography (LP-GPC) and semipreparative strong-anion exchange (SAX) fast ...
